What should the fuel pressure be on a 280z?

The fuel pressure for a Datsun 280Z typically should be around 30 to 36 psi (pounds per square inch) at the fuel rail. It's important to check the specifications for your specific model year, as slight variations might exist. If you’re troubleshooting, ensure the pressure is within this range while the engine is running and that it holds steady when the engine is off.
